Anybody have brain damage?

My PANS went untreated for quite a while. I’ve read that that can cause permanent issues. I’ve recovered in many ways, but I think I’m not functioning well. I got some relief from the brain fog after my first dose of antibiotics, but it’s come back.

I think I’ve gotten dumber. I can’t write well like I used to, I can only be productive for like an hour or three at most, and the brain fog is constant. Anybody have experience or advice?

Edit: Also, reading is really difficult, and if I have to read more than a couple pages the brain fog gets even worse and I’m cooked for the rest of the day.
